Comment:

 I agree with filosofo. Here's a snippet that practically does what you're
 asking for:

 {{{
 function my_posts_where( $where, $wp_query ) {
   if ( $wp_query !== $GLOBALS['my_wp_query'] )
     return $where;

   // this will only execute for $my_wp_query
 }
 add_filter('posts_where', 'my_posts_where', 10, 2);

 global $my_wp_query;
 $my_wp_query = new WP_Query(' ... ');
 }}}
